Inability to Walk Predicts Death among Adult Patients in Hospitals in Malawi.

ABSTRACT:

Objective

Vital signs are often used in triage, but some may be difficult to assess in low-resource settings. A patient's ability to walk is a simple and rapid sign that requires no equipment or expertise. This study aimed to determine the predictive performance for death of an inability to walk among hospitalized Malawian adults and to compare its predictive value with the vital signs-based National Early Warning Score (NEWS).

Methods

It is a prospective cohort study of adult in-patients on selected days in two hospitals in Malawi. Patients were asked to walk five steps with close observation and their vital signs were assessed. Sensitivities, specificities, and predictive values for in-patient death of an inability to walk were calculated and an inability to walk was compared with NEWS.

Results

Four-hundred and forty-three of the 1094 participants (40.5%) were unable to walk independently. In this group, 70 (15.8 %) died in-hospital compared to 16 (2.5%) among those who could walk: OR 7.4 (95% CI 4.3-13.0 p<0.001). Inability to walk had a sensitivity for death of 81.4%, specificity of 63.0%, positive predictive value (PPV) of 15.8%, and negative predictive value (NPV) of 97.5%. NEWS>6 had sensitivity 70.9%, specificity 70.6%, PPV 17.1%, and NPV 96.6%. An inability to walk had a fair concordance with NEWS>6 (kappa 0.21).

Conclusion

Inability to walk predicted mortality as well as NEWS among hospitalized adults in Malawi. Patients who were able to walk had a low risk of death. Walking ability could be considered an additional vital sign and may be useful for triage.

Project description:OBJECTIVE:To assess the value of the inability to walk unassisted to predict hospital mortality in patients with suspected infection in a resource-limited setting. METHODS:This is a post hoc study of a prospective trial performed in rural Rwanda. Patients hospitalized because of a suspected acute infection and who were able to walk unassisted before this disease episode were included. At hospital presentation, the walking status was graded into: 1) can walk unassisted, 2) can walk assisted only, 3) cannot walk. Receiver operating characteristic (ROC) analyses and two-by-two tables were used to determine the sensitivity, specificity, negative and positive predictive values of the inability to walk unassisted to predict in-hospital death. RESULTS:One-thousand-sixty-nine patients were included. Two-hundred-one (18.8%), 315 (29.5%), and 553 (51.7%) subjects could walk unassisted, walk assisted or not walk, respectively. Their hospital mortality was 0%, 3.8% and 6.3%, respectively. The inability to walk unassisted had a low specificity (20%) but was 100% sensitive (CI95%, 90-100%) to predict in-hospital death (p = 0.00007). The value of the inability to walk unassisted to predict in-hospital mortality (AUC ROC, 0.636; CI95%, 0.564-0.707) was comparable to that of the qSOFA score (AUC ROC, 0.622; CI95% 0.524-0.728). Fifteen (7.5%), 34 (10.8%) and 167 (30.2%) patients who could walk unassisted, walk assisted or not walk presented with a qSOFA score count ?2 points, respectively (p<0.001). The inability to walk unassisted correlated with the presence of risk factors for death and danger signs, vital parameters, laboratory values, length of hospital stay, and costs of care. CONCLUSIONS:Our results suggest that the inability to walk unassisted at hospital admission is a highly sensitive predictor of in-hospital mortality in Rwandese patients with a suspected acute infection. The walking status at hospital admission appears to be a crude indicator of disease severity.

Project description:BackgroundThe immigrant population across Europe is ageing rapidly. Nurses will likely encounter an increasing number of patients who are older adult immigrants. Moreover, access to and equal provision of healthcare is a key issue for several European countries. The relationship between nurses and patients is asymmetrical with unequal power relations; however, the way nurses construct the patient through language and discourse can help maintain or change the balance of power. Unequal power relations can affect access and be a hindrance to equal healthcare delivery. Hence, the aim of this study is to explore how older adult immigrants are discursively constructed as patients by nurses.MethodsAn exploratory qualitative design was used. Data were collected through in-depth interviews with a purposive sample of eight nurses from two hospitals. The nurses' narratives were analysed using critical discourse analysis (CDA) as described by Fairclough.ResultsThe analysis identified an overarching, stable, and dominant discursive practice; 'The discourse of the other', with three interdiscursive practices: (1) 'The discourse on the immigrant patient versus an ideal patient'; (2) 'The expert discourse'; and (3) 'The discourse of adaption'. Older immigrant adults were constructed as 'othered' patients, they were different, alienated, and 'they' were not like 'us'.ConclusionThe way nurses construct older adult immigrants as patients can be an obstacle to equitable health care. The discursive practice indicates a social practice in which paternalism overrides the patient's autonomy and generalization is more prevalent than a person-centred approach. Furthermore, the discursive practice points to a social practice wherein the nurses' norms form the basis for normal; normality is presumed and desirable. Older adult immigrants do not conform to these norms; hence, they are constructed as 'othered', have limited agency, and may be considered rather powerless as patients. However, there are some examples of negotiated power relations where more power is transferred to the patient. The discourse of adaptation refers to a social practice in which nurses challenge their own existing norms to best adapt a caring relationship to the patient's wishes.

Project description:BackgroundThe Philippines is ranked 3rd globally for tuberculosis incidence (554/100,000 population). The tuberculosis ward at San Lazaro Hospital, Manila receives 1,800-2,000 admissions of acutely unwell patients per year with high mortality. Objectives of this prospective cohort study were to quantify the association of under-nutrition (primary) and diabetes (secondary) with inpatient mortality occurring between 3-28 days of hospital admission in patients with suspected or previously diagnosed TB.Methods and resultsWe enrolled 360 adults (≥18 years); 348 were eligible for the primary analysis (alive on day 3). Clinical, laboratory, anthropometric and enhanced tuberculosis diagnostic data were collected at admission with telephone tracing for mortality up to 6 months post-discharge. In the primary analysis population (mean age 45 years, SD = 15.0 years, 70% male), 58 (16.7%) deaths occurred between day 3-28 of admission; 70 (20.1%) between day 3 and discharge and documented total post-day 3 mortality including follow-up was 96 (27.6%). In those in whom it could be assessed, body mass index (BMI) ranged from 11.2-30.6 kg/m2 and 141/303 (46.5%) had moderate/severe undernutrition (BMI<17 kg/m2). A sex-specific cut-off for mid-upper arm circumference predictive of BMI<17 kg/m2 was associated with inpatient Day 3-28 mortality in males (AOR = 5.04, 95% CI: 1.50-16.86; p = 0.009; p = 0.032 for interaction by sex). The inability to stand for weight/height for BMI assessment was also associated with mortality (AOR = 5.59; 95% CI 2.25-13.89; p<0.001) as was severe compared to normal/mild anaemia (AOR = 9.67; 95% CI 2.48-37.76; p<0.001). No TB specific variables were associated with Day 3-28 mortality, nor was diabetes (HbA1c ≥6.5% or diabetes treatment). Similar effects were observed when the same multivariable model was applied to confirmed TB patients only and to the outcome of all post-day 3 in-patient mortality.ConclusionThis research supports the use of mid-upper arm circumference for triaging acutely unwell patients and the design and testing of nutrition-based interventions to improve patient outcomes.
